What is self-assert?
self-assert is a small TypeScript library that helps you model valid domain objects and assisting their creation through guided assistants.
It encourages expressing validation inside the domain model — not in external schemas, UI forms, or controllers. This results in software that is easier to evolve, test, and reason about.
Inspired by object-oriented design principles, the library promotes:
- Encapsulation of rules inside your domain objects
- Valid construction over defensive validation
- Clarity and consistency across the system
